I have two Mini Bow Desktop Aquarium Kit's, the 2.5g's and they both have the filter's on, one's been set up for almost a year and the other has been running for a few month's now.

The current is a bit strong on them and my betta's do get pushed around by it, im mostly worried about Jasper, my oldest, he's been living with that current for almost a year now but he's not as young as he was back then.

I read on here advice that we could take the filter's out...i'm just wondering if i take them out where and how do i store them...
or should i just leave the filter's in and think of a baffle for the current...
I don't wanna harm my tank to much by playing with the filter so any advice would be appreciated...

I was wondering the same thing. I have a minibow 5G though. Finn gets pushed a little but he also likes to swim against the current. I tried an experiment where the farther the water is from the little waterfall that is produced, the weaker the current is. So perhaps lowering the water level a little may help?
Any other advice?

I did try that once and it was ok, i loved seing that waterfall and hearing the noise from it, but when i asked on here if it was ok people told me that it was not, it put unecessary strain on the filter.
